Abstract

A closure unit for a machine handling injection moulding material, esp. a plastic injection moulding machine, has a force transmitting frame (1) consisting of a lower connecting base (2) with a side member (3, 4) on each side. One side member (4) carries a tool support plate (5) while the other (3) has a header plate (9) with a sliding tool support plate (6). Actuators (10, 11) between the header plate (9) and the tool support plate (6) provide a force for opening and closing the tool (7, 8). At least two actuators (10, 11) are arranged at different heights relative to the base plate (2) so that slight deflections of the force transmitting frame (1) are compensated by differential movements (x1,x2) of the actuators (10, 11) in order to obtain a constant closing force distribution over the contact plane of the tool halves (7, 8). Pref. hydraulic cylinders (10, 10', 11, 11') are arranged at the four corners of the tool support plate (6). The tool support plate (6) runs along a guide plate (12) which is attached to the other tool support plate (5) so that the guide plate (12) does not deflect with the frame (1) under the closing forces. All the hydraulic cylinders are fed from a common supply under the same pressure and the compensating movements (x1,x2) take place automatically. Alternatively separately controlled hydraulic pressures can be applied to the upper (10) and lower (11) cylinders to deal with tools with asymmetric mould cavities.
